How do I do this problem "Find the values of a, b, c, and d that make the equation true."?

(ax^3-3x^2+2bx-2)-(2x^3-cx^2-5x-4d) = x^2+x-6











THANKS!

How do I do this problem "Find the values of a, b, c, and d that make the equation true."?
bring all the same powers together on the left side like:





(-3+c)x^2+ .. = x^2+x-6





then equate the coefficient of every power:





above:


-3+c = 1
